In the letter, the word is underlined, and at the top of the document is written: There was a very clear policy in the architecture office that words such as "gas chamber" should not be used; Second Lieutenant Kirschnek should be informed of this slip.

Sensitivity Heinrich Himmler became increasingly concerned about the security of documenting the destruction of the Jews. On April 9, 1943, he wrote a secret letter to Heydrich's successor as chief of the Gestapo and SD, Ernst Kaltenbrunner, concerning the Korherr Report. Himmler considered the report "well executed for purposes of camouflage and potentially useful for later times." The next day, Rudolf Brandt passed a message to the author of the report, Richard Korherr, stating: Himmler was so sure that almost everyone knew what "special treatment" meant, and ordered for it to be replaced with the even more vague ("guided through"), even though the document in question was top secret. The camps in question in the General Government were Treblinka, Sobibor and Belzec extermination camps, and Majdanek concentration camp. The only camp in the Warthegau was Chełmno extermination camp.

Later he expanded his explanation to point out that "special treatment" also included auxiliary measures besides killing: In his memoir , written in prison, he further commented on the meanings of , explaining that it had both a clearly lethal meaning as well as other possible ones and providing documentary examples for each meaning.
